This video shows the ContourGT-K 3D optical microscope for high-resolution surface metrology from Bruker Nano Surfaces. The ContourGT-K uses white light interferometry to determine surface topography ...

The optical microscope relies on light and consists of two main lenses: • The objective lens, which magnifies the object you wish to observe (with various magnification options). • The eyepiece, which ...

Researchers have shown that consumer-grade 3D printers and low-cost materials can be used to produce multi-element optical ...

Input and modulation of many different parameters are essential for other competitive ‘single measurement mode’ methods to produce better results on various surface textures in the same field of view ...

Schematic of the transmission mode microsphere superlens integrated with a classical optical microscope. The spheres collect the near-field object information and form virtual images that can be ...

Optical microscopy is a technique employed to closely view a sample through the magnification of a lens with visible light. This is the traditional form of microscopy, which was first invented before ...

Light can be focused by conventional far-field optics to a spot that is limited by diffraction to ∼0.5 λ/NA where λ is the wavelength and NA is the numerical aperture of the lens. The near-field ...

University of Manchester scientists have produced the world’s most powerful optical microscope, which could help understand the causes of many viruses and diseases. Writing in the journal Nature ...

Scientists boost the accuracy of optical microscopes to image microdroplets in flight and apply the method to analyze the concentration of plastic nanoparticles. Sneezes, rain clouds, and ink jet ...
